Explanation:
Noble gases are group O elements and their atomic structure ensures that they are stable. All their orbitals are completely filled with electrons therefore they do not undergo reactions with other elements.
- Heavier noble gases are able to form a range of compounds due their sizes.
- Elements form compounds by exchanging or sharing of their outermost shell electrons called the valence electron.
- Every atom has specific energy required to remove electrons from them. The energy is known as the ionization energy.
- In bigger atoms which have large radius, the outermost electrons have low ionization energy which makes them easy to remove.
- The ionization energy depends on the nuclear charge, the more the charge the higher the ionization energy. Down a group the nuclear charge and ionization decreases.
- As we go down the inert group, the ionization energy of outer shell electrons become very low. This makes the electrons available to take part in chemical reactions.

In order to find density, you need to divide mass/volume
Hey there!
Electrons are negatively charged and orbit the nucleus of the atom on energy levels (kind of in a cloud) :)
